WebAug 23, 2024 · A longer contact time results in more effective disinfection. As the chlorine concentration increases, the required contact time decreases. Chlorination is more effective at a high temperature and a low pH. Particles in the water decrease the effectiveness of chlorination, as microorganisms may ‘hide’ behind particles and avoid disinfection. WebThe addition of chlorine to water produces hypochlorous acid. This chlorine species is the most active in bactericidal effect, and is predominant from pH 4 to 7. Cl2 + H2O → HOCl + H+ + Cl− Increasing pH converts hypochlorous acid to hypochlorite, and the latter species predominates above pH 8. HOCl + OH− → OCl- + H2O
